To all whom it may concern Be it known that we, MAX P. MILLER and HAL T. PATTON, both citizens of the United States, and residents of Cleveland Heights, county of Cuyalioga, State of Ohio, and of ,Clevelend, county of Cuyahoga, State of QlllO, respectively, have jointly invented a 116W and useful Improvement 111 Valves for Steam Systems, of which the following 2,.

specification, tie principle of the invention rein explained and the best mode in which cove center lplzitetl applying that princlpic, to (iTtHJg'eilSl'l it from other inventions,

The present invention involves certain iin provements in steam traps for use in steam Heating s stems. The device is particularly designed for use in a steam line and is intended for automatic operation, depending upon the conditions existing in the line, To

the accomplishment of the foregoing and related ends, said invention, then, consists o? the moons hereinafter lt'olly described particularly pointed. out in the claims.

, R The annexed drawing and the following description set forth in detail certain neck-- asisxn embodying the invention, closed means constituting, liowev bait one of various me hanical forms in 'tbicb principle of the invention may be used.

In said annexed drawing The single figure there appearing is s central vertical section through our improved valve. V

@111- improved valve consists ot a suitable tubule? casin 1, having a lateral extension 2 for connection to a steam line, and a bottom extension 3, also i tended for suitable connection to a steam 51236. The casing of course includes an open passage between the parts 2 and 3 of the device, and in this open passage is mounted a valve seat 4. Directly above the valve seat 4, for operation in alignment therewith, is a conical valve 5 adapted to be seated against the edge of the seat under certain conditions. This valve 5 is iemovably attached to a'plug or member 6 which is firmly held in a disk shaped connecting member 7 attached to the bottom of an expensiblc metal bellows 8. The metal bellows, which is provided with a series of encir ling corrugations, permitting it to have a considerable expensive actiomis conl n I nected to, and closed at Its upper end b a plug 9, which is remotf'ably engaged Wit a .member 10 which serves as a cap orcover for the casing 1. The metal bellows and the valve are thus removed, along with the cover, and may be inserted in the valve casing as a gqei'bof the cover, and are then brought into alignment with the valve seat l.

The bellows is reduced in size and closed at its lower sod leaving an annular rib or corrugation formed on its lower outer periphery, The interior of rib 13 provides a groove is which is received a ring or collar 16 adapted to strengthen the lower end of "the bellows. The upper end of the valve 8 is provided with an enlarged annular flange which is adopted to lie adjacent the rib 13. The connecting member or trusto-conicel dis; 7 is engaged with both the rib 13 on the bellows and with the on the valve in such a as to hold the valve firmly sgairist' tli fist lower end of the bellows.

1 llormally the ialve 5 is spaced from seat and the steam line through the casing is open. these conditions water may drain from the conned-ion. 2, through the valve casing out through concoction 3, but on any ap bio sm'ount of steam entering the casing 1 it will act to expand the metal bellows member 8, which will move tbs valve 5 downwardly into engagement with the seat and time closes the line through. the casing Mounted Witbin'tbe sylplion bellows,

' upon the bottom end of the is a s or tube 11, provided with openings 11- therethrough to permit of tree circulation of the contents of the bellows, and this tube serves to maintain the valve 5, even when open,

only a certain distance from its seat, and generally to stiilen the bellows and. cause its contraction to proceed in a straight line and prevents any warms? contacts against. the p ug is contracted.

A. lii guid is chosen which Will operate under the conditions which make it necessary for The top of course v a closing of the line, and for ordinary pmposes we prefer to uses small amount of ale l0l or similar material. The best trons iii mitied to alcohol through she cormge'betimetal wall, oi the bellows serves to miss the temperature of the alcohol one to volatilize. li producing a considerable expansive force which is exerted downwardly to press the valve 5 firmly against ios seat 4%. soon. so

I

The lower 02 closed end of the bellows is sireogthenetl by being made of thicker metheii *nhe corrugated portion While we have found that 2 Wall thickness of about iiiiie ihouseiiciths an inch is sufficient for the corrugations, and in fact gives better flexibility than can be secured with a greater ihiclmess, the end vis desirably formed of materiel having an thickness of from thirty five to forty thousendtlis A heilovvs so coostiucieei has been found to have longer life soil. so be less liable to breakage than one having the some Wall thickness throughout.

" A further improved feature is met this lower end is integral with the corrugated portion and the absence of goints also lessees the danger of ieekege or breakage.

additional advantage consists in the assembly of the thermostatic member as apart of she GOV/81"..
